CHARLES W. ELLSWORTH, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CHICAGO STAMPING COMPANY, OF SAME PLACE.

SHEET-M ETAL-CAN TOP.

SPECIFICATION forming part of Letters Patent No. 263,326, dated August 29, T882, Application tiled July 15, 1882. (No model.)

To all whom it may concern Be it known that I, CHARLES W. ELLs- WORTH, of Chicago, in the county ot' Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Metal- Can Tops, of which the following, 1n connection with the accompanying drawings, is a specication.

In the drawings, Figure l is a side view, shown partly in section, of a sheet-metal can embodying my improvements. Fig. 2 is a central cross-section of the permanent portion ot' the top ofthe can. Fig. 3 is a like reprcsentation of the severable portion of the top. Fig. 4 is a like view of the permanent and severable parts arranged for being locked together, and Fig. 5 is a central cross-section of all the top parts arranged together.

Like letters of reference indicate like parts.

M v invention relates to that class of sheetmetal cans which are provided with tops in which a disk of thin or soft metal or paper is secured, and my object is to connect the permanent and the severable parts of the top to each other with facility, which purpose I accomplish in the manner substantially such as is hereinafter described and set forth.

A represents the body of the can.

B is an annular ring or permanent part of the can-top, and C is the severable cover, ot' thin or sol't metal or paper.

D is the removable lid or slip-cover.

The part B may be secured to the body A in any well known or suitable way, and is made annular in form, having a large circula-r open; ing therein, as indicated in the drawings.

a is avertical upturned flange or rim on the part B, and a is a horizontal liange on the cover C. The cover C is such in form and size as to adapt it tittingly to enter the opening, ot' which the iiange t is the rim, and is sut'tieiently deep or dishing to depend a little way below the horizontal portion ot' the part B when the flange a rests on the flange a, as a is clearly indicated in Fig. 4.

To secure the part C to the part B, I place them in a die and setdown thelange aagainst the side of the flange a, as shown in Figs. 1 and 5, and part C is also thus expanded below the part B, as shown at a, a bead or horizontal iiange being so formed there .as to operate, in conjunction with the flange a', in keeping the severable part C in firm connection with the permanent part B, and at the same time rendering the joint tight. I then fasten the top thus made to the body of the can, which should first receive its contents. I then apply the lid or cap D, which is flanged, as

shown at b, to t the vertical seam formed by uniting the parts B and C. The can is now ready for shipment, and when it reaches its destination the slip-cover D may be removed and the part C severed by being cut around near its junction with the part B. The slipcover D may then be applied, as before, to cover the contents exposed by cutting the part C away.

Such a top will be found to be very serviceable as a top for cans in which to ship paints and like goods. It is to be understood that the part C is to be made either ot' paper or, preferably, ot' soft metal, or of metal suffi ciently thin to he cut or severed with facility. The slip-cover D protects the severable part or seal C during transportation, and also serves as a cover or lid when the can is unsealed for USC.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the permanent annular ring B, provided with the inner upturned tlange or rim, a, the severable cover C, provided with the flange a", extending underneath the part B, and the iiange c', turned down upon the flange a, substantially as and for the purposes specified.
